Negligent infliction of emotional distress
The tort of negligent infliction of emotional distress (NIED) is a controversial cause of action, which is available in nearly all U.S. states but is severely constrained and limited in the majority of them. The underlying concept is that one has a legal duty to use reasonable care to avoid causing emotional distress to another individual.
